Re: [sumo-user] Loading simulation state fails after collision (stop on

[Marcelo Andrade Rodrigues D Almeida <md@xxxxxxxxx>]

Yeah, I see!

I don't know what happened last time, but I invalidated the docker build cache one more time and the source from yesterday presented no problem (SUMO v1_8_0+0390-debec094ac)

Thank you

Sincerely,

All the attached states were written by version 1.8.0 but they need to be written by the latest development version (check the first comment line in the file).

Thank you

I just tested with the latest development version

RUN curl https://sumo.dlr.de/daily/sumo-src-git.tar.gz \

| tar -xz

ENV SUMO_HOME=sumo-git

RUN mkdir sumo-git/build/cmake-build && cd sumo-git/build/cmake-build \

&& cmake ../.. && make -j$(nproc)

I'm still finding the same error (I don't know if it is the same cause, though)

See attached save states

Error:

Hi everyone

I was running my application and found this error (Sumo version 1.8.0):

"Error: stop for vehicle '-gneE0__gneE3__light.42' on lane ':gneJ0_2_0' is not downstream the current route.
Quitting (on error).
'Connection' object has no attribute '_socket'"

This error occured after loading a state, saved after the following collision:

Step #1830.00

Warning: Vehicle '-gneE0__gneE3__light.42'; collision with vehicle '-gneE2__gneE0__light.46', lane=':gneJ0_2_0', gap=-1.00, time=1830.00 stage=move.

To reproduce the error locally, I loaded the state manually in my machine

Loading through python, I receive pretty much the same error, but for car 46 instead.

Alternatively, if I try to load it through the sumocfg and sumo-gui, I receive this error:

sumo files + script attached

Thank you in advance

Sincerely,

Marcelo d'Almeida
